Title: Improvements in synchronous mechanical clutches
IPC: F16D23/08
Filed: 1947-03-19
Abstract: 625,476. Claw clutches. VICKERS-ARMSTRONGS, Ltd., and WOOD, G. March 19, 1947, No. 7607. [Class 80 (ii)] Sliding of one claw clutch member along its shaft to engage the co-acting member is prevented, until the driving and driven speeds cross, by a balking nut screwing along an extension of the shaft between the members under the action of a friction washer connected to the second member by spring means. In one form, a nut 17, Fig. 1, screwing on a threaded extension 14 of the driven shaft 2 co-acts frictionally with a ring 19 connected to the driving shaft 1 by a spring 18 and prevents manual or other advancement of the slidably splined driven clutch member 6 into engagement with the driving clutch member 4 until the driven shaft overhauls. The ring 19 may be connected to the driving shaft by an extension sleeve slidably splined thereon, the spring 18 being then free at both ends. In a modified form having additional means to prevent engagement below a predetermined speed of the driving shaft, a centrifugal latch 24, Fig. 4, coacting with a skirt 171 on the nut 17, balks the advance of the driven clutch member 6 until the nut has advanced sufficiently to bring an annular groove 27 thereon opposite the latch. The latch then releases the member 6 provided the driving shaft is rotating fast enough to urge a piston 30 linked to the remote end of the latch outwards into a cylindrical recess 31 which is filled with damping oil, expelled as through a bleed groove 301 in the piston as the latter advances. Expelled oil is retained centrifugally in a recess 32. There may be a symmetrically arranged plurality of latches 24. A multiple start thread of square section may be used on the extension 14. Reference has been directed by the Comptroller to Specification 624,180.

Patent GB-1579349-A (GB)
Title: Components resistant to corrosion at high temperatures
IPC: C22F1/10
Filed: 1977-02-24
Abstract: In order to protect components of gas turbines against high-temperature corrosion, especially sulphidation, without substantially reducing the mechanical properties of the base material as a result of excessive temperatures during heat treatments, the components, which consist of austenitic base material on the basis of nickel, cobalt or iron, are provided with a protective layer which consists of two components. One of these components is a material resistant to said corrosions, while the second component is a metal alloy which melts at a lower temperature than the first component and whose melting range is between 950 and 1300 DEG C. In the novel protective layer, the hard particles of the first component are uniformly dispersed in the softer material of the second component and are anchored to the base material so as to adhere strongly thereto. The preparation of the protective layer involves melting the second component at least partially by heat treatment; the maximum temperature of the heat treatment in the process is at most 50 DEG C above the standard solution annealing temperature of the base material. Consequently, temperatures which are unacceptably high for the base material are avoided during the heat treatment.

Title: Improvements in or relating to apparatus for measuring and detecting the level of electricity-conducting material
Inventor: DAVIDSON DANIEL FRASER
IPC: G01F23/24
Filed: 1955-03-18
Abstract: 793,953. Electric tests. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. March 2, 1956 [March 18, 1955], No. 7894/55. Class 37. The level of a conductive liquid 14 in a conductive tank 10 is determined by a metal probe 13 which dips into, and is insulated from, the tank, the arrangement being that probe, liquid, and tank constitute an inductance which with condenser 15 forms a series resonant circuit. This circuit is fed from the output of an oscillator 27 the frequency of which is variable by knob 28 calibrated in terms of depth of liquid, through a coaxial cable 22, condenser 20 and potential divider 16-17. The voltage developed across divider section 17 in parallel with the resonant circuit is rectified at 18, smoothed by condenser 19 and fed through the coaxial cable to meter 26 in series with limiting resistance 25. Oscillator 28 is adjusted until a dip in the reading of meter 24 indicates resonance when the oscillator frequency indicates the depth of the liquid. Alternatively condenser 25 may be varied while the oscillator frequency is constant. The working frequency must be so chosen as to avoid ambiguities such as arise when probe 13 acts as a half-wave line.
